Malaseb Shampoo 250 ml is a clinically proven pet prescription medication UK formulated to treat bacterial and fungal skin infections in dogs and cats. It is widely prescribed by veterinarians to manage seborrhoeic dermatitis and to help eliminate ringworm (Microsporum canis) when used alongside environmental decontamination.
This medicated shampoo contains a dual-action combination of miconazole nitrate (antifungal) and chlorhexidine gluconate (antibacterial). Together, these ingredients remove infection-causing microorganisms, restore skin balance, and reduce itching, scaling, and redness.
Clinical uses of this Pet prescription medication
Veterinary studies confirm that Malaseb controls mixed bacterial and yeast infections of the skin, particularly those involving Staphylococcus intermedius and Malassezia pachydermatis – two common causes of canine dermatitis. It also supports treatment of ringworm infections in cats when combined with systemic antifungal therapy and strict hygiene measures.
Because it removes surface debris and excess grease, it helps active ingredients reach the deeper layers of the skin where infection often persists. Consistent use promotes a healthy coat, reduces unpleasant odour, and improves comfort.
Active ingredients and composition of this Pet prescription medication
Each millilitre contains:
Chlorhexidine gluconate 20 mg (as chlorhexidine 11.26 mg) – a broad-spectrum bactericide that damages microbial cell membranes.
Miconazole nitrate 20 mg (as miconazole 17.37 mg) – an imidazole antifungal agent that disrupts fungal cell-wall synthesis.
Excipients include surfactants, conditioning agents, and fragrance to aid penetration and leave the coat manageable.
How to use this Pet prescription medication
Wet the coat thoroughly with clean lukewarm water.
Apply Malaseb Shampoo to the skin and massage gently until a rich lather forms.
Ensure coverage of affected areas such as between toes, under the tail and around the lips.
Leave the lather on for 10 minutes to allow active ingredients to work.
Rinse thoroughly and dry with a clean towel in a warm environment.
For dogs with seborrhoeic dermatitis, apply twice weekly until clinical signs resolve, then reduce to once weekly or as directed by your vet. For cats with ringworm, use twice weekly alongside oral antifungal therapy and environmental cleaning.

Scientific data supporting this Pet prescription medication
Independent veterinary trials show that Malaseb significantly reduces microbial counts and improves skin scores in dogs with dermatitis after two to four weeks of use. In fungal studies, combined systemic and topical therapy achieved faster clearance of ringworm spores compared with systemic therapy alone. These results confirm its role as an essential adjunct treatment for bacterial and fungal infections.
